Back-End Software Engineer

Union Technologies is reindustrializing America’s defense manufacturing base with a first-of-its-kind Factories-as-a-Stockpile™ model, integrating advanced robotics, manufacturing, and software into sovereign factory systems at scale. Headquartered in Dallas, Texas, UNION is dedicated to restoring America’s industrial strength and guaranteeing deterrence for the century ahead.

We recently emerged from stealth with $50M in funding led by top-tier venture investors and strategic partners. Read more in our Press Release

Why This Role ExistsOur manufacturing software platform is scaling rapidly, and we’re growing the team to help build and operate reliable backend services in Go. You’ll work closely with senior engineers to design, test, and deploy the services and data models that turn live machine and process data into traceable production insights.

This is an opportunity to develop deep technical skills in distributed systems, data modeling, and industrial software—while learning from engineers who have built production systems at scale.

What You’ll Do• Implement and maintain Go services (REST/gRPC) for tracking work orders, parts, and quality records. 

• Build and test event-driven data flows using Kafka and other messaging tools. 

• Write SQL queries and data models in PostgreSQL and related databases. 

• Collaborate with edge and data engineers to integrate telemetry from industrial machines. 

• Contribute to observability and reliability through metrics, traces, and structured logs. 

• Follow best practices for secure software development (RBAC, encryption, least privilege). 

• Participate in code reviews, technical discussions, and cross-functional planning. 

• Continuously learn new tools and technologies in a production manufacturing environment.

The Stack You’ll Work With• Languages/Frameworks: Go, chi/Echo, gRPC, Protocol Buffers 

• Messaging/Streams: Kafka, Schema Registry, Protobuf 

• Data: PostgreSQL/TimescaleDB, Neo4j, Redis 

• Platform: Kubernetes, Helm, Terraform, GitHub Actions 

• Observability: OpenTelemetry, Prometheus/Grafana, Loki 

• Security: Vault, TLS/mTLS, OAuth2/OIDC, CMMC L3-aligned practices 

Required Qualifications• 1–3 years of experience building backend applications (academic, internship, or professional). 

• Some familiarity with Go (or similar languages like Rust, C++, or Java) and willingness to learn Go deeply. 

• Basic understanding of APIs, databases (SQL), and containerized environments. 

• Eagerness to learn event-driven systems, observability, and DevOps fundamentals. 

• U.S. Person per ITAR and willing to undergo background screening for DoD clearance.

Preferred Qualifications• Exposure to manufacturing, industrial automation, or IoT data systems. 

• Familiarity with Kafka, message queues, or event streaming. 

• Experience deploying or troubleshooting applications in Kubernetes. 

• Interest in cybersecurity and compliance frameworks (CMMC, NIST 800-171). 

• Desire to grow into a mid-level engineer capable of owning service areas and mentoring others.

What Success Looks Like After 12 Months• You’ve contributed production-quality code to multiple backend services in Go. 

• You confidently debug issues across the data flow (from event to database). 

• You understand how our systems interact—data models, APIs, and pipelines. 

• You’ve helped improve our development and testing workflows. 

• You’re recognized by your peers as dependable, curious, and a fast learner.

Join the mission. We'll handle the move.Exceptional talent shouldn't be bound by geography. If you're ready to relocate to Dallas, TX and join us in reindustrializing America’s defense backbone, we'll make it easy—and for those who move quickly, additional incentives may be available.
